(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

show f(x)=x^3-3x^2+2x is not one to one on (-infinity,+infinity)

2. Relevant equations

finding the largest value of k such as f is one to one on interval (-k,k)

3. The attempt at a solution

i can get f`(x)=3x^2-6x+2 but it is positive so f(x) should be one-to-one

how to prove it
